问题 共用题干Time in the Animal World

Rhythm controls everything in Nature._______(46)The sun provides a basic time rhythm for all living creatures including humans.Nearly all animals are influenced by sun cycles and have developed a biological clock in their bodies following these cycles.The moon also exerts its force and influence on the sea. Its gravitational attraction causes the rising of the tide._______(47)When the moon is behind the Earth,centrifugal force causes the second tide of the day.
Animals living in tidal areas must have the instinct of predicting these changes,to avoid being stranded and dying of dehydration.Since the time of the dinosaurs,the king crab has been laying eggs at the seaside in a set way.To avoid predator fish,the eggs are always far from seawater and protected by sand.In the following two months,the eggs undergo dramatic changes related to the cycles of the moon.When the second spring tide comes,the young king crabs have matured._______(48)
Most of the mammals,either the giant elephant or the small shrew,have the same average total number of heartbeats in their lifetime.Shrews live only for two and a half years,and spend their life at a high speed and high tempo.Animals like shrews with a pulse rate of 600 per minute have an average total of eight hundred million heartbeats throughout their life.The African elephant has a pulse rate of 25 beats per minute,and a life span of 60 years.The size of the body determines the speed of life._______(49)
As we get older,our sense of time is being influenced by the physiological changes of our body.The elderly spend more time resting,and do few sports._______(50)For a child,a week is seen as a long time._________（48）A:For an adult,time goes fast year by year.B:It controls,for example,the flapping of birds' wings,the beating of the heart and the rising and setting of the sun.C:The larger the animal is,the longer its life span is and the slower its life tempo is.D:The tide goes out when the moon moves away and its attraction is weaker.E:We always tend to think all the animals have the same sense of time as human beings.F:The second spring tide takes them back to the sea.
选项 _________（48）
A:For an adult,time goes fast year by year.
B:It controls,for example,the flapping of birds' wings,the beating of the heart and the rising and setting of the sun.
C:The larger the animal is,the longer its life span is and the slower its life tempo is.
D:The tide goes out when the moon moves away and its attraction is weaker.
E:We always tend to think all the animals have the same sense of time as human beings.
F:The second spring tide takes them back to the sea.
答案 F
解析 本空前文提到：节奏控制着自然界中的一切事物，是主题句。空中所填内容应该是陈述主题句的细节。选项B" It controls, for example, the flapping of birds' wings, the beating of the heart and the rising and setting of the sun.”例如，它控制着鸟类翅膀拍击、心跳和日出与日落，这句是用来说明主题句的例子。controls是两个句子的词汇连接手段，两个句子的内容也连贯。所以B是答案。
本空前文提到：月亮对大海施加力量和影响，其地心吸力造成涨潮。空后的句子涉及第二次涨潮。可以推断，位于这两个句子之间的所要填的内容应该与大海和潮汐有关。选项D说的是退潮。所以选项D是正确答案。
本空前文提到：生长在潮汐地区的动物具有预测潮汐的本能。然后以国王螃蟹为例。螃蟹远离海岸产卵，并将之埋在沙下，防止食肉鱼吞食。到第二次春潮来临时，小螃蟹已破壳而出。选项F第二次春潮会把他它们带回大海，其中出现second spring，这是与上一句联系的信号。从内容上看，它是上一句意思的自然发展。所以选项F是正确答案。
本空前文提到：哺乳动物不管寿命长短、体形大小，其一生心跳总次数大致相同。作者举体形大、寿命长的大象和体形小、寿命短的尖鼠为例说明。本段的倒数第二句是结论：The size of the body determines the speed of life．体型的大小决定生命的速度。由此可以推理出本空所填内容应该与上述结论有关。选项C动物的体型越大，它们的寿命就越长，生命节奏也就越慢，这一内容是对上一句的结论的细化说明。所以选项C是正确答案。
第四段说到随着年龄的增长，生理变化会影响人的时间感。本空前面一句说到老人，后面一句说到小孩。由此可以判断，本空的内容会涉及另一个年龄段。选项A 对成年人来说，时间一年一年地过得很快，其中提到了成年段。所以选项A是正确答案。
